Abstract: An adjustable folding utility tray for removable attachment to a tripod comprising a portable frame with attached collapsing or folding members is provided. The folding utility tray removably attaches to two legs of an easel or tripod. Once the device is positioned at the desired operational height, two slidingly attached arms are adjusted to engage and contact the easel or tripod legs. After use, the device is folded, or collapsed, into a compact size for transport or storage and removed from the easel or tripod.

Abstract: The present disclosure is directed to an oxygen delivery system that distributes oxygen-enriched air around a patient's head and face without requiring a physical connection to the patient. The oxygen is distributed by the system through one or more fluid outputs, which are operatively connected to an oxygen supply line either directly or indirectly through at least one fluid transmission line, manifold or plenum. This directed oxygen mixes with the air surrounding the patient to produce an oxygen-enriched environment at the exit side of the fluid outputs.
